Meshmixer really is the ultimate tool for remixing 3D models. In order to learn about some of the new features that have been added, the 123D team got together to jam. We made some musical mashups based on remixes of 3D models from our gallery - and we'd love to share with you how we did it.
We made five different band members, using different techniques. From left to right: Beethoven Mechaspider, the Elefan, Guitar Golem, Keytar Kritter and Horndog.
The Mechaspider combines a model created in 123D Design, the Mechanical Tarantula, with a scan created with 123D Catch, Beethoven's head. We used the new Make Solid feature in Meshmixer to turn the spider model into a single unified part. You can adjust the resolution and accuracy of this operation until you get something that works. We added the model of Beethoven to the same project, and used the Inspector feature to close any gaps. Finally, we positioned the head using the Transform tool, and used the Boolean Union operation to join everything together.
The Elefan started off with the Elephant Conductor model from the 123D Content Library, which is perched on a music box base. The Plane Cut function sliced off the base. Then we added a Hook'em Horns Hand, used Mirror to get two of them, and used Transform to size them and position them appropriately. Finally, selecting hands and body, and applying a Boolean Union pulled it all together.
Guitar Golem starts with the Wood Golem and the Guitar Antenna topper, both from the 123D Content Library. The first order of business was to load both models into Meshmixer, and size them correctly relative to each other. The guitar has a cylindrical fitting that we don't need, so we used Select mode in Meshmixer to select and delete. We needed to pose the Golem so we used one of the hot new features in Meshmixer - the Soft Transform. First select the parts of the limb that we want to move, then choose Deform -> Soft Transform, and select the Non-Linear option. This treats the boundary between the selection and the body as if it were rubber, and makes for a really nice way to pose models.
Keytar Kritter is based on the Metal Golem and the Keytar. Once again, the new Make Solid tool was key to make the Keytar into a single solid piece. Soft Transform came in handy to pose the Golem, adjusting both the arm position and the fingers to make it look like he is really rocking out.
Finally, Horndog starts with the Ghostbusters Terror Dog made in 123D Creature, combined with the Tambourine around its neck and the Bugle for ears. We used Make Solid and Boolean Union as before (see a pattern?) but then applied a major new feature. The Tambourine and the Bugle have very fine details that would not print well, so we went to the new 3D Print area in Meshmixer, and used the Adaptive Thickening option to make sure that there were no details less than 2mm in size.
All the models were printed on our fancy Objet 3D printers here at 123D secret headquarters, but the advanced support options in Meshmixer will let you print on a Makerbot or other affordable printers. Give Meshmixer a try - it's free, and should be an essential part of your toolbox if you're doing anything with 3D printing!
